cpuidle: psci: Opt-out from genpd's common ->sync_state() support
The cpuidle-psci-domain implements its own specific ->sync_state()
callback. Let's set the GENPD_FLAG_NO_SYNC_STATE to inform genpd about it.
Moreover, let's call of_genpd_sync_state() to make sure genpd tries to
power off unused PM domains.
